There has been a rapid growth of scientific literature on the application of computational fluid dynamics (CFD) in the research of ventilation and indoor air science. With a 1000-10,000 times increase in computer hardware capability in the past 20 years, CFD has become an integral part of scientific research and engineering development of complex air distribution and ventilation systems in buildings. This review discusses the major and specific challenges of CFD in terms of turbulence modelling, numerical approximation, and boundary conditions relevant to building ventilation. We emphasize the growing need for CFD verification and validation, suggest ongoing needs for analytical and experimental methods to support the numerical solutions, and discuss the growing capacity of CFD in opening up new research areas. We suggest that CFD has not become a replacement for experiment and theoretical analysis in ventilation research, rather it has become an increasingly important partner.
We believe that an effective scientific approach for ventilation studies is still to combine experiments, theory, and CFD. We argue that CFD verification and validation are becoming more crucial than ever as more complex ventilation problems are solved. It is anticipated that ventilation problems at the city scale will be tackled by CFD in the next 10 years.
未加标签：计算流体动力学（CFD）在通风和室内空气科学研究中的应用方面的科学文献呈快速增长趋势。在过去的 20 年中，计算机硬件能力增长了 1000-10000 倍，CFD 已经成为复杂空气分布和建筑通风系统科学研究和工程开发的不可或缺的一部分。本文讨论了 CFD 在湍流建模、数值逼近和与建筑通风相关的边界条件方面的主要和具体挑战。我们强调了 CFD 验证和验证的日益增长的需求，建议为支持数值解需要持续进行分析和实验方法，并讨论 CFD 在开辟新的研究领域方面的日益增强的能力。我们认为，CFD 并没有取代通风研究中的实验和理论分析，而是成为了一个越来越重要的合作伙伴。
实际意义：我们认为，通风研究的有效科学方法仍然是将实验、理论和 CFD 结合起来。我们认为，随着解决越来越复杂的通风问题，CFD 验证和验证变得比以往任何时候都更加重要。预计未来 10 年 CFD 将用于解决城市规模的通风问题。
